A police bomb squad was called to California's Pebble Beach golf course when an apparent explosive device was found near the links, authorities said.
 
A beachcomber reported early Sunday he had found what looked like two pipe-bombs taped together at the base of a 40-foot cliff near the Monterey, Calif., course's 9th hole, Bay City News reported Monday.

The Monterey County Sheriff's Office called in a bomb squad, which examined the suspicious-looking device and rendered it safe.

Investigators said they could not determine for sure what it was, but it appeared to be configured in a way similar to explosives, KSBW-TV, Salinas, reported.

Authorities said the incident remained under investigation.
